The much talked about dating show Love Island is back after 18 months away and this year's fashion trend had viewers confused.
As a new batch of singletons lined up to meet their matches, fans couldn't help noticing a new craze sweeping the TV villa.
The underboob top is already a big hit with fashionistas and it's found its way into the ladies' suitcases.

As the stunning singletons took their places around the pool viewers took to Twitter to have their say.
"What’s with all the under boob?" asked one fan.

"Ok can we talk about this underboob situation?! Is this a thing now or am i just getting old?" asked another.
"You can tell I’m the wrong side of 25 cause if I tried one of them underboob bikinis I’d look like a kilogram of potatoes spilling out the bottom of an Asda plastic bag," remarked another viewer.
"I see under boob is the theme this year!" remarked another.

"These underboob bikinis look so uncomfortable," another viewer wondered.
"There’s so much underboob this series," tweeted another fan.
"I have learned that Underboob is the current craze in beachwear," remarked another.

Another Love Island fan asked "Feel old…what is it with all of this underboob bikini thing about?" while another questioned: "When did underboob replace cleavage?"
Love Island has returned for its seventh series as brand new Islanders seek to find their perfect match.
They will do their best to flirt, date, couple up and try and avoid being ‘dumped’ from the Mallorcan villa.
There will be more texts, fire pit gatherings and challenges for the lovestruck Islanders, all narrated by the voice of Love Island, Iain Stirling.
Because of the coronavirus pandemic Love Island was last on our screens for its first winter series in January 2020 and there was no summer series last year.
The winter edition in South Africa was won by Paige Turley and Finley Tapp who moved in together in Manchester.
Love Island is screened at 9pm on ITV2 and ITV Hub.
Episodes are available the following morning on BritBox.
